Get installed programs on iOS devices

There are three situations:

1. For devices after jailbreak, you can obtain the complete list, which is convenient. The method is as follows:
Http://stackoverflow.com/questions/3878197/is-it-possible-to-get-information-about-all-apps-installed-on-iphone/3878220#3878220

Http://www.iphonedevsdk.com/forum/iphone-sdk-development/22289-possible-retrieve-these-information.html

 

You can also obtain the following code:

Nsfilemanager * filemanager = [nsfilemanager defaultmanager]; nsmutablearray * applist = [[nsmutablearray alloc] init]; nsstring * apppath = @ "/var/mobile/Applications "; for (nsstring * path in [filemanager contentsofdirectoryatpath: apppath error: Nil]) {for (nsstring * subpath in [filemanager contentsofdirectoryatpath: [nsstring stringwithformat: @ "% @/% @", apppath, path] error: Nil]) {If ([subpath hassuffix :@". APP "]) {nsstring * infoplist = [nsstring stringwithformat: @" % @/info. plist ", apppath, path, subpath]; nslog (@" info. plist PATH % @ ", infoplist); nsdictionary * dict = [nsdictionary dictionarywithcontentsoffile: infoplist]; nslog (@" configuration file content of this app % @ ", dict ); [applist addobject: [dict objectforkey: @ "cfbundledisplayname"] ;}} nslog (@ "applist: % @", applist); [applist release];

Directory:/applications/

2. There are no jailbreaking devices and no APIs are provided officially. Therefore, you can only use some tips, but the information is incomplete.

Here are two methods:
Method 1: Use URL scheme to check whether the URL scheme exclusive to an application has a response. If there is a response, it indicates that this specific app is installed.
Method 2: Use some methods to obtain information about the currently running process, and obtain information about the installed app from the process information.

Another method that should be feasible is to determine whether or not some software is installed. For this method, refer to this article:

Http://www.iloss.me /? P = 835 but in general, it is not easy to obtain the complete installation list without jailbreak.

First, the study in this article must be on the premise of jailbreak.

There are currently three methods to List Installed Software in IOS: (as far as I know)

1. There are two methods for obtaining my previous articles. For more information, see:
Http://www.iloss.me /? P = 844
2. the functions provided by the system should be more convenient, safe, and efficient than the above two methods. (According to my test system, the file com. Apple. Mobile. Installation. plist is also read)
Mobile installation is the IPA framework installed, uninstalled, and updated in IOS.
Obtain the following API

Here I will only analyze the _ mobileinstallationbrowse

Finally, paste the final analysis result:

INT (* mobileinstallationbrowse) (nsdictionary * options, INT (* callback) (nsdictionary * dict, id value), id value );

Call method:

Static int callback (nsdictionary * dict, Id result) {nsarray * currentlist = [dict objectforkey: @ "currentlist"]; If (currentlist) {for (nsdictionary * appinfo in currentlist) {[(nsmutablearray *) Result addobject: [[appinfo copy] autorelease] ;}} return 0 ;}+ (ID) Browse {nsmutablearray * result = [nsmutablearray new]; mobileinstallationbrowse ([nsdictionary dictionarywithobject: @ "any" forkey: @ "applicationtype"], & callback, result); // any indicates all programs, here we can use "system" and "user" to distinguish between systems and common software}

The final result array will be the list of programs we have obtained. The structure is in plist format, as shown below:

This is the same as the result of the first method.
